Abstract (from CDS):

We report the discovery of two transiting extrasolar planets from the HATSouth survey. HATS-11, a V=14.1 G0-star shows a periodic 12.9 mmag dip in its light curve every 3.6192 days and a radial velocity variation consistent with a Keplerian orbit. HATS-11 has a mass of 1.000±0.060{M}_☉, a radius of 1.444±0.057{R}_☉ and an effective temperature of 6060±150 K, while its companion is a 0.85±0.12{M}_{J}, 1.510±0.078{R}_{J} planet in a circular orbit. HATS-12 shows a periodic 5.1 mmag flux decrease every 3.1428 days and Keplerian RV variations around a V=12.8 F-star. HATS-12 has a mass of 1.489±0.071{M}_☉, a radius of 2.21±0.21{R}_☉, and an effective temperature of 6408±75 K. For HATS-12b, our measurements indicate that this is a 2.38±0.11{M}_{J}, 1.35±0.17{R}_{J} planet in a circular orbit. Both host stars show subsolar metallicities of -0.390±0.060 dex and -0.100±0.040 dex, respectively, and are (slightly) evolved stars. In fact, HATS-11 is among the most metal-poor and, HATS-12, with a log{g}_* of 3.923±0.065, is among the most evolved stars hosting a hot-Jupiter planet. Importantly, HATS-11 and HATS-12 have been observed in long cadence by Kepler as part of K2 campaign 7 (EPIC216414930 and EPIC218131080 respectively).
